Getting a duplex water softener is necessary if you have hard water in a large home with a lot of demand. Regular single tank softeners can treat enough hard water for the average 1-3 family home.
A two tank system means that it can cope with a larger volume of water needs. This is because the machine never has to stop working as one tank will rest while the other is working.
What is hard water and why is it a problem?
Hard water is when “hard minerals” like calcium and magnesium ions are present in water and causes white limescale stains in and around your kitchen / bathroom appliances.
The simple way to know if you suffer from hard water is look inside your kettle. If it is full of white and flaky scales at the bottom then you have hard water.
It is not great to consume lots of hard water from a health perspective but the bigger problem is what hard water does to your pipes and appliances.
The only guaranteed way to treat hard water is with a water softener. There are many softener types on the market that include simplex, duplex and triplex.
A Simplex Water Softener System
These are by far the most common type of water softener that you can buy on the market today and are usually the cheapest too.
Simplex water softeners are best for situations where there is a steady demand for moderate capacities of soft water in a day.
This allows you to regenerate when you reliably know that soft water will not be needed (usually late at night).
The Biggest Flaw?
The main disadvantage of a simplex water system is that it can not produce soft water 24-7 like the other types of softener systems.
What is a Duplex Water Softener?
Duplex water softeners are high capacity softeners that are suitable for dealing with high levels of hard water and locations that need an uninterrupted supply of softened water.
They do this with 2 tanks instead of 1. Hence the name “duplex”, which comes from “duo” – the latin word for 2.
Duplex softeners typically come with a controller, which allows you to set the beginning of the regeneration cycle with the timer, the quality of the water or the quantity produced.
Duplex Water Softener Tips:
Water softeners are generally very reliable devices. However, a low level of regular attention is necessary to make sure that they provide good service over a longer period of time.
- You should consider getting a routine professional service by an experienced service team. This will ensure the safety and continued high quality operational performance of your machine.
- A timed or automated device works best when the daily need for soft water is relatively constant. You simply have to set the duplex softener machine to regenerate when overall consumption is low (usually late at night).
- On the other hand, counter-controlled (on demand) models are ideal when daily water demand is variable.
- High-purity softener salt is necessary to ensure the smooth running of the brine tank.
Triplex Water Softener System
As the name suggests, a triplex system is a water softener that has 3 tanks.
This is usually a bespoke system but there are a few triplex water or heavy duty softeners available for immediate purchase online.
A bespoke model might combine a simplex system combined with a duplex system. This means there can also be customized quadplex or multiplex water softeners.
Triplex systems are commonly used in the industry where production requires a sudden influx of softened water at peak times. If necessary, two of the three tanks will start regenerating to meet a spike in demand.
The third container is then available as soon as the other two resin beds are exhausted.
The Best Duplex Water Softener System?
As has been mention a duplex system is one that consists of two tanks containing ion softeners.
This unit is particularly useful in a commercial or industrial environment where closing a production line for 2 hours would seriously effect the bottom line.
You can normally control Duplex softeners by the meter.
Duplex Water Softener Price?
You can get a twin duplex water softener for upwards of $2300.
Also, you benefit from free next day delivery, an Amazon accredited plumber to install it for you which means you can theoretically have your very own duplex water softener installed by the end of tomorrow.
Finally, their customer service is far better than that provided by many water companies so you have access to extra support if anything goes wrong.
But remember that most machines that come from places like Pelican come with guarantees and lifetime warranty.
